Description

Method and device for adjusting service rate

The present application claims priority to Chinese Patent Application No. 201510315149.3, entitled "Adjustment Method and Apparatus for Service Rate" on June 10, 2015, the entire contents of which are incorporated herein by reference. .

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a method and an apparatus for adjusting a service rate.

Background technique

With the development of data communication and multimedia services, fourth-generation mobile communications, which are adapted to mobile data, mobile computing and mobile multimedia operations, are beginning to emerge. The 4th Generation mobile communication technology (4G) includes Time Division Long Term (TD-LTE) and Frequency Division Duplexing Long Term (FDD-LTE). ) Two systems. 4G integrates 3G and WLAN, and can quickly transmit data, high quality, audio, video and images.

Voice over-LTE (VoLTE) is an LTE voice solution based on the IP Multimedia Subsystem (IMS) network. VoLTE is essentially different from 2G and 3G voice calls. VoLTE is the architecture. End-to-end voice solution under all IP conditions on 4G networks.

FIG. 1 is a signaling diagram of an existing VoLTE call flow signaling interaction. As shown in FIG. 1 , a user equipment (User Equipment, UE for short) uses a Session Initiation Protocol (SIP) signaling to a Proxy-Call Session Control Function (referred to as a Proxy-Call Session Control Function). The P-CSCF/Session Border Controller (SBC) sends an INVITE message, where the INVITE message includes codec information; where, for the Adaptive Multirate Narrow Band (AMR-NB), the broadband self-band Adapted to the multi-rate (AMR-WB) codec, the message carries the rate set information supported by the UE. The IMS sends the INVITE message to the peer end, that is, the codec information is sent to the peer end, and the voice bearer codec negotiation is performed through the SIP signaling. Then, the P-CSCF/SBC receives the response message 180 of the peer end feedback, and the response message 180 carries the codec information of the bearer plane returned by the peer end. The P-CSCF/SBC sends the response message 180 to the UE. Therefore, through the SIP signaling negotiation, the UE, the P-CSCF/SBC, and the peer device learn the codec information used in the current call, and if it is the AMR-NB, AMR-WB codec, the rate set information is also obtained. Subsequently, after the call is connected, the bearer plane interaction is performed according to the result of the SIP signaling negotiation. In the above process, an evolved NodeB (eNB), a Serving Gateway (S-GW), or a PDN Gateway (P-GW) transmit signaling and bearer messages. A signaling and bearer GPRS tunneling protocol (GTP tunneling) is established between the eNB and the S-GW/P-GW. When receiving the uplink packet sent by the UE, the eNB transmits the uplink packet through the GTP tunnel. The S-GW/P-GW is sent to the S-GW/P-GW to send the uplink packet to the P-CSCF/SBC. When the P-CSCF/SBC sends a downlink packet to the UE, the downlink packet is sent to the S-GW/P-GW, and the S-GW/P-GW sends the downlink packet to the eNB through the GTP tunnel. Passed to the UE through the air interface.

In the all-IP voice solution, the eNB and the S-GW/P-GW are only responsible for transmitting IP packets (including signaling and bearer). The voice solution of the all-IP mode cannot be transmitted according to the air interface of the eNB. The quality of the service is dynamically adjusted, which may cause the problem that the actual transmission capacity of the eNB does not match the service rate, resulting in packet loss, long delay, or low resource utilization.

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 2 is a schematic diagram of a network architecture according to an embodiment of the present invention. The network architecture of the embodiment of the present invention is an LTE network architecture. Specifically, the user equipment (User Equipment, UE for short) accesses an Evolved Packet Core (EPC) through an evolved Node B (eNB). The EPC includes a plurality of network entities, such as a Mobility Management Entity (MME), an S-GW, a P-GW, and the like. The connection relationship between the network entity in the EPC and the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) is specifically: the MME is connected to the eNB, the S-GW is connected to the eNB, and the MME and the S-GW are connected. Connected, the S-GW is connected to the IMS through the P-GW. The IMS includes a P-CSCF/SBC, a Serving Call Session Control Function (S-CSCF), and a Home Subscriber Server (HSS). The specific P-CSCF/SBC is connected to the P-GW and the S-CSCF respectively, and the S-CSCF is also connected to the HSS and the Application Server (AS). Under the network architecture, the main functions of the eNB include: radio resource management functions (ie, implementation of radio bearer control), radio admission control and connection mobility control; IP header compression and encryption of user data streams; MME selection when UE attaches status Implementing routing of S-GW user plane data; performing scheduling and transmission of paging information and broadcast information initiated by the MME; completing measurement and measurement reports related to mobility configuration and scheduling. The main functions of the MME include: encryption and integrity protection of Non-Access Stratum (NAS) signaling; Access Stratum (AS) security control, idle state mobility control; Evolved Packet System (EPS) bearer control; supports paging, handover, roaming, authentication, etc. The main functions of the S-GW include: packet data routing and forwarding; mobility and handover support; lawful interception; billing. The main functions of the P-GW include: packet data filtering; IP address allocation of the UE; uplink and downlink billing and speed limit.

Among them, the Call Session Control Function (CSCF) can be divided into three types: P-CSCF, S-CSCF and I-CSCF according to its location and function. Among them, P-CSCF (Proxy CSCF): is the first connection point with the user in the IMS, providing a proxy (Proxy) function, that is, accepting the service request and forwarding the accepted service request. S-CSCF (Serving CSCF): The S-CSCF is in the core control position of the IMS core network. It is responsible for registration authentication and session control of the UE, and performs basic session routing functions for the calling and called IMS users. According to the IMS triggering rule signed by the user, the value-added service route triggering and service control interaction to the AS are performed when the condition is met. I-CSCF (Interrogating CSCF): An IMS-like gateway node that provides local user service node assignment, route query, and IMS inter-domain topology hiding.

The HSS is a centralized information database for storing IMS users in the home network, including basic identification, routing information, and service subscription information. The AS (Application Server) provides IMS value-added services for IMS users. The AS can be located on the user's home network or by a third party.

It should be noted that the P-CSCF and the SBC may be separately or combined. Normally, the P-CSCF is combined with the SBC. Therefore, the SBC in the embodiment of the present invention may be a physical device that is a P-CSCF and an SBC, or may be a separate SBC device, which is not limited thereto.

The present invention implements the service rate adjustment of VoLTE based on the network architecture of FIG. 2, and the details of the following embodiments are explained in detail.

FIG. 3 is a flowchart of Embodiment 1 of a method for adjusting a service rate according to the present invention. The execution subject of the embodiment is an SBC. As shown in FIG. 3, the method in this embodiment may include:

Step 101: Receive actual transmission capability information of the base station sent by the base station.

The actual transmission capability information may include air interface current transmission quality information or air interface desired service rate information. The current transmission quality information of the air interface may be specifically that the current transmission quality of the air interface is good, the current transmission quality of the air interface is normal, the current transmission of the air interface is slightly abnormal, the current transmission of the air interface is abnormal, or the current transmission of the air interface is abnormal. The traffic rate information expected by the air interface can be a specific rate value. The rate value is used to reflect the size of the data transmission capability that the base station can provide for the user's data service, so as to fully utilize the air interface resource to transmit the service data. The traffic rate information expected by the air interface may be obtained by the base station according to the traffic volume and transmission quality of the cell.

Specifically, the base station acquires the actual transmission capability information of the base station, and the base station sends the actual transmission capability information of the base station to the SBC. The base station may obtain the actual transmission capability information in real time, which is an implementable manner. The base station sends the obtained actual transmission capability information to the SBC in real time. In another achievable manner, the base station obtains the current actual transmission capability information in real time, and compares the actual transmission capability information with the last acquired actual transmission capability information. Different from the actual transmission capability information acquired last time, the base station sends the current actual transmission capability information of the base station to the SBC. That is, the base station may send its own air interface to the SBC after learning that the quality of the air interface between the base station itself and the terminal changes. Transmit quality information or service rate information expected by the air interface. How to set it up can be flexibly set according to your needs.

Step 102: Perform adjustment processing on the service rate of the sending end according to the actual transmission capability information and the service rate of the sending end of the service packet sent to the base station.

Specifically, according to the received actual transmission capability information, in combination with the service rate of the transmitting end that sends the service packet to the base station, the service rate of the transmitting end is adjusted. The service rate of the sending end of the service packet sent by the base station is the service rate obtained by the SBC to unpack the service packet, and the service rate is specifically the size of the service packet to be delivered per second. For example, the example in which the voice service is initiated by the terminal is used as an example. If the actual transmission capability information of the base station is a slight abnormality in the current transmission of the air interface, the service rate of the sender transmitting the service packet to the base station needs to be reduced. The sender is the terminal, that is, the service rate of the terminal needs to be reduced. Specifically, how much the service rate of the terminal is reduced or decreased, and the data transmission is performed at a large service rate, and the codec rate set information of the terminal needs to be combined. The codec rate set information includes a plurality of rate information supported by the terminal, for example, for an Adaptive Multirate Narrow Band (AMR-NB) codec, the AMR-NB has eight rates: 4.75K, 5.15. K, 5.90K, 6.70K, 7.40K, 7.95K, 10.2K, 12.2K, as shown in Table 1, for the Adaptive Multirate Wide Band (AMR-WB) codec, the AMR-WB has 9 Rate: 6.6K, 8.85K, 12.65K, 14.25K, 15.85K, 18.25K, 19.85K, 23.05K, 23.85K, as shown in Table 2, specifically, the terminal can support one or more of them, ie The codec rate set information of the terminal may be lower than the service rate before the adjustment process and belong to a rate of the codec rate concentration when the service rate of the terminal needs to be reduced.

Table 1

Table 2

Different from the prior art, in this embodiment, the SBC can obtain the actual transmission capability information of the base station, and the SBC can be combined with the actual transmission capability information of the base station according to the obtained service rate of the transmitting end that sends the service packet to the base station. The service rate of the sender is adaptively adjusted. Therefore, the service rate of the transmitting end of the service packet sent to the base station is matched with the actual transmission capacity of the base station, thereby improving the data transmission quality.

Further, in the process of implementing the VoLTE, the data received by the base station may be an uplink service packet sent by the terminal, or may be a downlink service packet sent by the core network. The uplink service packet is sent by the terminal. Specifically, the terminal sends the uplink service packet to the base station, and the base station sends the uplink service packet to the core network, so the service packet is sent to the base station for the uplink service packet. The sending end is the terminal; the downlink service packet is sent by the SBC. Specifically, the SBC sends the downlink service packet to the base station through the S-GW and the P-GW in the core network, so the downlink service packet is sent to the base station. The sender of the service packet is the SBC. For the different senders that send service packets to the base station, the SBC performs different service rate adjustment processes. The service rate adjustment processing in different cases will be described in detail below.

1. If the sending end of the service packet is sent to the base station, and the terminal sends an uplink service packet to the base station, in step 102, according to the actual transmission capability information, and sending a service packet to the base station. The service rate of the sending end is adjusted, and the service rate of the sending end is adjusted, and the service rate of the terminal is increased or decreased according to the actual transmission capability information, and the service rate after the lifting or lowering is obtained; The terminal sends a speed adjustment request message, where the speed adjustment request message includes the upgraded or reduced service rate.

Specifically, the base station allocates an air interface transmission resource to transmit a service packet, and the actual transmission capability of the base station may be expressed as the actual amount of data that the base station can transmit per second. For example, when the amount of data that the base station can transmit per second is large, the actual transmission capacity of the base station is good, and when the amount of data that the base station can transmit per second is small, the actual transmission capability of the base station is poor. The actual transmission capability may be better. The current transmission quality of the air interface of the base station is better, or the service rate expected by the air interface is higher, and the specific data can be set to be greater than a threshold value per second, then the actual When the transmission capacity is good and the amount of data that can be transmitted per second is less than a threshold, the actual transmission capability is poor. Of course, it can be understood that a certain range can also be set, and each range corresponds to different actual transmission capabilities. For example, setting the first range corresponds to the actual transmission capability, and the range can be a numerical interval, and the amount of data that can be transmitted by the base station per second. Within the first range, the actual transmission capability is better. It should be noted that the specific threshold and range setting can be flexibly set according to requirements, and only for illustrative examples. Further, when the actual transmission capability is good, the service rate can be improved, so that the terminal uses a higher service rate to transmit data; when the actual transmission capability is poor, the service rate can be reduced, so that the terminal can transmit the service report by using a lower service rate. Therefore, the problem of multiple packet loss and long delay caused by the poor transmission capacity of the base station and the high rate of the terminal service can be reduced.

The actual transmission capability information of the base station can be obtained through the foregoing steps, and according to the actual transmission capability information, it is learned that the service rate of the terminal needs to be adjusted accordingly, and the specific adjustment process, that is, how to complete the service rate and the lower service rate, The following explanation is required. The service rate information that the actual transmission capability information is expected to be an air interface is exemplified. The eNB may notify the SBC of the service rate information expected by the air interface. Assume that the expected traffic rate information of the air interface is 12.5K, and the SBC can select a similar service rate: if the current AMR WB encoding mode is adopted and the terminal supports According to Table 2, the service rate similar to the traffic rate information 12.5K expected by the air interface is 12.65K, and the SBC informs the terminal that the adjustment rate is 12.65K; if the current AMR NB coding mode is adopted and the terminal supports According to Table 1, all the rates of the AMR NB coding mode are 12.2K, which is similar to the service rate information 12.5K expected by the air interface. The SBC informs the terminal that the adjustment rate is 12.2K.

The transmission quality information whose actual transmission capability information is an air interface is exemplified. The eNB notifies the SBC of the information about the good transmission quality of the air interface, and if the current AMR WB coding mode is adopted and the terminal supports all the rates of the AMR WB coding mode, the SBC can improve the service rate of the terminal as much as possible because the transmission quality of the air interface is good. According to Table 2, the maximum rate of the AMR WB coding mode is 23.85K, and the SBC informs the terminal that the adjustment rate is 23.85K. In the same coding mode, when the eNB notifies the SBC of the normal transmission quality of the air interface, the SBC The notification terminal adjusts the rate to 12.65K. In the same coding mode, when the eNB notifies the SBC of the abnormal transmission quality of the air interface, the SBC informs the terminal that the adjustment rate is 6.6K, that is, the SBC reduces the service rate of the terminal as much as possible. In this embodiment, the actual transmission capability information is the transmission quality information of the air interface, and after the SBC obtains the transmission quality information of the air interface, how to adjust the service rate of the terminal can be flexibly set according to requirements. The foregoing is only an example, and is not As a limitation. It can be understood that, for example, when the rate of the AMR WB coding mode is 6.60K, 15.85K, and 23.0K, when the eNB notifies the SBC of the good transmission quality of the air interface, the SBC informs the terminal that the adjustment rate is 23.0K. When the eNB notifies the SBC of the information about the normal transmission quality of the air interface, the SBC informs the terminal that the adjustment rate is 15.85K. When the eNB notifies the SBC of the abnormal transmission quality of the air interface, the SBC informs the local side that the adjustment rate is 6.60. K, that is, different rates correspond to different air interface transmission quality information.

It can be seen that the specific principle of adjusting the service rate can be flexibly set according to requirements, and the above example is not limited thereto.

2. If the sending end of the service packet is the SBC, that is, the SBC sends the downlink service packet to the base station, in step 102, the service message is sent to the base station according to the actual transmission capability information. The service rate of the sending end is adjusted, and the service rate of the sending end is adjusted. Specifically, if the SBC does not perform the codec conversion process, the service rate of the peer end is raised or decreased according to the actual transmission capability information. Sending a speed control request message to the peer end, where the speed control request message includes an increased or decreased service rate.

It should be noted that the sending end of the service packet to the base station is the SBC, that is, the SBC sends the downlink service packet to the base station, and there are also two cases: 1. The SBC does not perform the codec conversion processing, and the SBC Perform codec processing. Whether the SBC performs the codec conversion process is performed according to the SIP signaling negotiation performed by the UE and the PEER in the background technology according to the call originating end and the call receiving end. For case 1, the speed adjustment request message is sent to the peer device by using the above steps. For the case 2, the step 102 may be specifically: if the SBC performs a codec conversion process, the service rate of the SBC is raised or decreased according to the actual transmission capability information, so as to increase and decrease the service rate. The terminal sends a service packet. That is, the SBC adjusts its own service rate, and sends a service packet to the base station at the service rate after the adjustment.

Further, in step 101, the actual transmission capability information of the base station sent by the base station is received, and the actual transmission energy is The MME sends a message to the MME, and the MME sends the message to the S-GW/P-GW, and the S-GW sends the message to the MME. The S-GW sends the message to the MME. The S-GW sends the message to the S-GW. The /P-GW sends the message to the PCRF, and the PCRF sends the message to the SBC, where the message may carry the actual transmission capability information of the eNB, that is, the current transmission quality information of the air interface or the service rate information desired by the eNB. It should be noted that the S-GW/P-GW is used to indicate the S-GW and the P-GW, and the S-GW and the P-GW may be separately configured. The corresponding implementation manner is: the eNB sends a message to the MME. The MME sends the message to the S-GW, and the S-GW sends the message to the P-GW, and the P-GW sends the message to the PCRF, and the PCRF sends the message to the SBC.

The SBC receiving the actual transmission capability information of the base station sent by the base station may be implemented by using another specific implementation manner. Specifically, the SBC receives the real-time transport protocol control protocol packet (Application-Defined RTCP) of the first defined application sent by the base station. The packet (abbreviated as RTCP APP) acquires the current transmission quality information of the air interface of the base station or the service rate information expected by the air interface in the first RTCP APP.

That is, the current transmission quality information of the air interface of the base station or the service rate information of the air interface is obtained by using the RTCP APP in the RFC3550. The "6.7APP: Application-Defined RTCP Packet" in the RCF3550 specifically describes the format and application of the RTCP APP, and the RTCP APP is a An application that can be defined by the user. If you receive an RTCP APP that you cannot understand, ignore the processing. The format of the specific RTCP APP is as follows:

Among them, the RFC is specifically called Request For Comments. It is a series of memoranda issued by the Internet Engineering Task Force (IETF). The document collects information about the Internet and software files of the UNIX and Internet communities. Numbering is scheduled. The common Internet Protocol RFC numbers are IP: 791, DHCP: 2131, SIP: 3261, RTP: 3550, and L2TP: 3931, etc., and the above steps of this implementation are modified on the basis of the existing RFC3550 to achieve The SBC can obtain the actual transmission capability information of the base station.

In this embodiment, when the actual transmission capability information of the base station is transmitted by using the RTCP APP, the subtype field is set to information indicating the transmission direction.

The parameter may be carried in the application-dependent data. area.

Specifically, between the eNB and the S-GW, between the S-GW and the P-GW, according to the GPRS tunneling protocol (GPRS tunneling) The protocol (GTP for short) establishes a GTP tunnel. After the eNB encapsulates the RTCP APP, the eNB sends the encapsulated RTCP APP to the S-GW through the GTP tunnel. The S-GW sends the encapsulated RTCP APP to the P-GW through the GTP tunnel. The P-GW performs decapsulation to obtain the RTCP APP, and sends the RTCP APP to the SBC.

That is, when the service rate is adjusted for the video service, the TMMBR sends or lowers the processed service rate to the terminal or the peer.

It should be noted that the TMMBR herein is specifically a message type defined in RFC5104.

Further, for the video service, the SBC may further receive a Temporary Maximum Media Stream Bit Rate Notification (TMMBN) for the temporary maximum media stream sent by the terminal or the peer end, and the temporary maximum media stream. The notification message of the bit rate is a response message of the request message of the bit rate of the temporary maximum media stream.
